is t. pasacana synonymous with t. atacamensis?

Wiki citing E.F.Anderson...

"There are two recognized subspecies. Subspecies pasacana is often branched, and occurs in Argentina and Bolivia. Subspecies atacamensis is usually unbranched, less tall (up to 6 m (20 ft) rather than 10 m (33 ft)), and is found in Chile."

I'm not sure it's so simple, but I don't have the answers. This is a group of plants needing some serious attention considering their wide range.

this was the source of my confusion, and the fact the t. pasacana wiki page redirects to t. atacamensis

[M S Smith]

Yeah, T. pasacana is currently considered a subspecies of T. atacamensis. I'm not sure of the name trail on this one, but I suspect there is plenty to chew on.

Borderline self-incrimination michael

Opps, my bad.

[Optimystic]

is this a Pascana chewing challenge?

Yes, both plants are synonymous and were placed under Echinopsis Atacamensis, divided by the two subspecies/varieties ssp. atacamensis and ssp. pasacana. There are Differences in the branching habit, but this is actually not enough to consider them two different Species. These are the type of differences that can occur when the same plant grows in two different Areas. You could also call them Regional Varieties.
